DUST-SEPARATING- OR VACUUM CLEANING APPARATUS.

Application led September 16, 1907. Serial No. 392,981.

To all whom fit may concern:

Be it known that I, LEMUEL WILLIAM SEREELL, a citizen of the United States, residing at Plainfield, in the county of Union and tate of New Jersey, have invented an Improvement in Dust-Separating or Vacuum Cleaning Apparatus, of which the following is a specification.

My invention relates in connection with pneumatic or vacuum cleaning devices, to means for moistening the dust of dust laden air previous to its passage into the wash box or liquid holding vessel, so as to insure a quick and ready mixture with, and taking up in suspension by the water of the wash box and the liberation of the cleaned air.

The device of my invention is located in the pneumatic or vacuum cleaning apparatus in theline of pipe between the place where the dust is collected and the wash box into which it is delivered, and in carrying out my invention, I employ a circular mixing vessel composed of two connected parts, into one of which a pipe enters for conveying the dust laden air or dirty water; the other or lower part of this mixing vessel is provided with a raised flanged center and lower chamber merging into a discharge pipe. A tubular boss enters this lower chamber and a pipe for water is connected therewith on the outside and the pipe of an internal member is connected to it on the inside and this internal member is composed of a disk and top plate and into the cavity formed between these parts, the water enters and is discharged by peripheral or marginal holes. This internal member is.

formed with a disk which fits tightly within the main vessel and the periphery of the disk is diagonally grooved or provided with ports through which the dust laden air or dirty water passes with appreciable and increased speed. The water holes preferably aline with the discharge openings of these diagonal ports so that the dust. of the dust laden air in passing through these diagonal ports, producesan atomizing effect upon the water and the dust is wet by the particles of the immerging water, so that the dust with the water and air all pass together down into the wash box or liquid holding vessel.

Tn the drawing, Figure 1 is a vertical section representing the devices of my improvemenu Fig. 2 is a plan of the disk portion of the internal member with its flange, and Fig. 3 a side elevation of the parts shown in Fig. 2.

a represents the upper part or member of the circular mixing vessel of dome shape with a flanged lower edge, and 2 a pipewhich enters the apertured center of said member for conveying into said vessel the dust laden air as gather-ed in cleaning, or dirty water collected in cleaning.

b represents the lower part or member of the circular mixing vessel with a flanged edge adapted to be connected to the lianged edge of the upper member, as shown in Fig. 1. This lower member is provided with a central circular ange b1 rising from the bottom of the vessel with a central discharge chamber 3 of small area in proportion to that of the mixing vessel. A tubular boss b2 extends into the discharge chamber and is internally threaded at its outer end to receive the pipe 6 for water and axially bored and threaded to receive the center pipe c2 and the lower end or part of the mixing vessel Z2 is apertured and threaded to receive the discharge pipe 4;.

c represents a disk formed in one piece with a center pipe c2 with a rising outer and flanged edge 01. This disk is provided with bo-sses bored and threaded for the bolts 7 which secure to the disk the top plate al, thus forming between the disk c and the top plate a water chamber to receive the water which enters by the pipe 6, the longitudinal passage-way 5 in the boss b2 and through the center pipe c2 and the disk is provided with series of small water holes 8 from which this water is discharged into the mixing vessel. The periphery of the iianged edge c1 of the disk c is diagonally grooved to provide surface ports 9. These agree by preference in number with the number of the water holes 8 and their lower discharge. ends substantially coincide with the mouths of these water holes. These diagonal ports form the only communicating passage-ways between the uppper part of this circular mixing vessel and the lower part, consequently the entire volume of dust laden air or dirty water is obliged to pass through these diagonal ports and in doing so, a circular motion at an increased speed is imparted thereto and the dust of the dust laden air is moistened by the water which immerges with some force from the holes 8, an atomizing effect having been feo- K of said pipe,

V`the dust-laden air,

given to the water. The supply of water passing through these holes from the pipes 6 and c2 is preferably under control and serves to replenish the water in any suitable water tank or liquid holding vessel and cause an overfiow of the same with the object of keeping this 'liquid holding` vessel as clean as possible. As the area of the discharge chamber 3 is small compared with that of themi-Xing vessel, this outlet causes a rapid action of the air and dust or dirty water as the same passes therethrough, which prevents lodgment of dirt.

In an application filed by me of even date herewith, I have shown and generally described the features of the present application, as I prefer to employ the devices of this application in connection with the apparatus of my copending application.

In the device Vof my improvement and where dirty or soapy water is being collectedV in cleaning, the water discharged from the water holes 8 serves. to dilute this dirty water and at the same time increase thel bulk of the water in the wash box or liquid holding vessel, so as to keep up the fiow in said vessel and the continuous discharge of the dirty water into the sewer.

I claim as my invention:

il. In a .pneumatic or vacuum cleaning apparatus and in combination, a pipe for the dust laden air, a vessel interposed in the line of and connected to adjacent sections a device within and extending across said vessel adaptedY to receive water, having openings connecting the chambers of said vessel at the opposite sides thereof for the passage of the dust laden air and `also provided with openings for delivering the water therefrom to be commingled with and moisten the dust.

3. In a pneumatic cleaning apparatus and in combination, a central pipe for the dust laden air, a hollow vessel interposed in the length of said pipe, a hollow diaphragm for water within said vessel having openings for discharging and distributing the water therefrom, means for conveying water into said hollow diaphragm and sai diaphragm provided with inclined peripheral grooves for the passage of the dust laden air whereby a circular motion and agitation is imparted to the air and water before passing out from the said hollow vessel.
